When an airline places a passenger in a class lower than that for which the ticket was bought they must refund a percentage of the ticket. The refund amount varies depending on the flight distance.

If the flight distance is:

• 1500km or less: 30% of the ticket must be refunded;
• 1500km – 3500km: 50% of the ticket must be refunded;
• Greater than 3500km: 75% of the ticket must be refunded.

If an airline places a passenger in a class higher (i.e. upgrading) than that for which the ticket was purchased, it may not request any supplementary payment.
